Config Parser module

Config parser --module for parsing configuration files

What is a configuration file?

Files that contain configuration program information are called configuration files

What kind of data should be used as configuration information

Information that needs to be changed but not changed for example: path to a data file

There are only two types of content in the configuration file:

　　One is section partitioning

One option is a key=value form

The most we've used is the get feature-used to get a configuration option from the configuration file

Examples are as follows:

# The contents of the test.cfg file are as follows: # path-dependent configuration  = c://myfile/test.txt#  user-related configuration  = Kogan #  service-related configuration   = 192.168.1.2
